UNITED STATES PATENT QIEFICl'i GEORGE BOOTH, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMEN'T IIN LUNCH-BOXES.

Specification forming part of Letters Patent No. 149,429, dated April 7, 1874; application tiled March 7, 1874.

To all whom 'it may concern: e

Be it known that I, GEORGE Boo'rn, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Lunclr Box; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 1n the art to which it pertains to make and use it, reference being had to the accompanyin g drawings, which form part of this speciication, in which is shown a perspective view of my invention.

This invent-ion has relation to lunch-boxes, and has for its object the production of a box which will, in appearance, closely resemble a book, and which will be dura-ble and of strength sufficient to resist the pressure of a book-strap.

The details of construction are fully set forth in the description and claims.

Referring to the accompanying drawings, A designates the rim or wall of the box, ot' which a single strip of tin is used to form the front and ends by being' bent at a', as shown. B B are ilanges turned inwardly from the upper and lower edges of said wall. O designates the bottom of the box, consisting of a sheet of tin, which is bent up and around at cl to form the back, and give the box the appearance of a book. Upon the end and front edges of the bottom O are bent the L-shaped flanges c, the inner portions of which extend above the lower edges of the wall A, forming close seams, strengthening the connection between the bottom and rim, and providing convenient means for the application of solder, of which but a small quantity will Vbe required, drops being placed at intervals and between the flanges 'of the said rim and bbttom. D designates the lid hinged to the ends ot' the box, the pivotal wires d beingsoldered to the latter, and bent around so as to pass under the hinge-plates d2, which may be made by slitting and bending ears, as shown, at the hinged edge of the lid, or by separate strips of tin soldered to the lid at both .their ends. The former style of plate is preferable, being more easily produced and stronger than the other. E is a concavoconvex flange, turned on the hinged edge of the lid. When the lid is closed this flange falls under the adjacent edge of the back d, and strengthens the box at that point. At c the lid is slightly indented or corrugated for the reception, when the lid is closed, of the inwardly-curving edge of the back, behind which the concave-convex iange lies. The latter is bent to the form shown to receive a pencil or other article of stationery. F represents L-shaped iianges similar to those on the bottom, and adapted to lit inside of and impinge tightly against the rim when the lid is closed. G is a bent strip, forming sockets for the reception of a rule and other articles, as shown. .At one end of the lid is an inclined plate, g, along which the rule slides when pushed out. The object of said plate is to cause the rule to rise according as it is drawn out, and thus avoid the obstruction of the lange of the lid. H indicates a post soldered to the bottom of the box, and designed to brace the lid and prevent it from being sprung out of shape by the book-strap.

Among' the advantages of the peculiar construction and arrangement of the lid above described may be mentioned, specially, the concealment of the hinges, whereby the similarity of the box to a bool( is rendered more perfect.

Having fully described my invention, I claim as new, and desire to secure by Letters Patentl. In combination with a lunch-box having a hin ged lid, F, and curved back d, the hinges consisting of the plates d2, bent inwardly from the lid at the ends thereof, and the pintles d1, soldered to the ends of the box and bent inwardl y, substantially as shown and described.

2. In combination with a lunch-box having the hinges formed of the plates d and pintles d1, located at the ends ot' the lid O, the post H, soldered to the bottom O about midway between the ends thereof, to support the inner edge of said lid, substantially as specified.

3. In a lunch-box, the bottom O, having the L-shaped flanges c and curved back d, and the wall A, composed of a single strip, formingI the front and sides, and flanged at B B', in combination with the hinged lid D, having concealed hinges and inwardly-bent iianges F, all constructed substantially as and for the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this 3d day ot' March, 1874.
